We are given a radical expression: [tex]\sqrt[3]{7x}[/tex].
We need to find which of the given options is like to given expression [tex]\sqrt[3]{7x}.[/tex]
Note: Here like doesn't meant be equal.
But like means here with similar radical.
We are given cube root in the given expression.
We can see first option [tex]4(\sqrt[3]{7x}[/tex] has a cube root and 7x inside cube root.
Therefore, [tex]4(\sqrt[3]{7x}) \ is \ like\ radical \ to \ \sqrt[3]{7x} .[/tex]
